Image 1; Maverick internals
The long-awaited Maverick is a cool gun out of the box, but because of its range, it's pretty much useless for me in a war. To solve this problem, I replaced the barrels in the turret with CPVC, and it can now get ranges of almost 50 ft.
First, open it up. You will need to remove the cocking slider to get at a screw underneath it.
Next, remove the turret. Push the release button and pull it out. To take it apart, remove the six screws and pull it apart. You'll have to pull really hard to get it apart. Make sure you keep your hands cupped around the end because there will be little orange caps popping off when it comes apart. When you have pulled it apart, it separates into these pieces.
You can throw away the orange air restrictors and barrel posts (not shown in the picture).
Now you need to saw off the barrels on the front turret piece. Cut them off right where they get smaller.
Then dremel out the tips of the barrels so CPVC can fit snugly in them.
Here's a pic of the dremel bit I used.
Next, you make the barrels. Cut 6 3-in. pieces of CPVC and file one end of each of them square. File out the other end to make loading darts easier.
The next step, gluing the barrels in, is rather tricky. Originally I just hot-glued them to the rear turret piece and reassembled the turret. However, due to excess glue around the seam, the turret would not fit together fully and was wider than before. This caused too much friction for the turret to rotate.
So I tried something different, and it worked. First I inserted each of the barrels into the two front turret pieces so the barrels were aligned with the top, like this.
Then I put hot glue around the rims of the barrels and quickly placed the rear turret piece on top of them. Make sure you line up the screw holes. Here's a pic of this.
Then press the turret together, insert the six screws and replace the pin. Make sure you put the little spring on the rod before you put the orange end cap on. You may need to tap the cap on with a hammer. If your barrels are not glued in perfectly, don't worry. A few of mine were still a little loose, so I ran a bead of hot glue around the muzzles of the barrels to secure them in the turret. If the glue sticks into the barrel, make sure that you trim it with a knife so it doesn't snag your darts. Here's a picture of the turret with glued barrels.
Once you have finished with the turret, reassemble it and put it back in the gun. Like removing it, you will need to press the turret release button to get it in. Before you put the casing on, you will need to put the slider half with the metal rod on. Make sure you hook the ring on the little spring onto the rod on the slider. It may help to refer to the internals and turret pieces pictures at the beginning of the mod.
Replace the casing and the other half of the slider, and you're done!
Now your Maverick should shoot farther and with more velocity. Personally, I like it for its outstanding ROF.
